How difficult is it for foreigners to find a job ? (Havana)

Hi, I am arriving in Cuba on 1st September from the UK with the intention of living and working there. From the few threads here and what I've been reading, it's not going to be easy to find employment. I have been teaching in International schools in Cambodia and Myanmar for the last 7rs. Previous work experience includes finance, property management and hospitality and I speak Spanish. I am just wondering if I should be working on Plan B now. Any leads, advice or tips will most appreciated ! Thank you !
